If you look at the millions of flight hours that the S-70 has flown since introduction, because it works. (Seahawk and Blackhawk share that common lineage).
For What It's Worth: not surprised that the lateral disturbance seems to have been related to dampers. In my experience, main rotor dampers were a source of never ending attention, and frustration, when I was in the Fleet around 30 years ago. I would need to dig into the NAVSAFCEN's data base on mishaps to dig out such ones as had dampers as a contributing factor, but it's been a long time since I was in a job that allowed me access to that.
I suspect that there is a little more to be learned on this. I'd love to see if any changes to the NATOPS were made for the CH-60S as a result (in terms of 'if you run into this, do that') instructions.
No further speculation will be made by me.
PS: thanks for the link,
the JAGMAN report will get a more thorough read from me later on.
